老化混凝土板分层弹性分析

为了更加准确地认识混凝土板劣化后的状态，根据实验得到的结果，建立了混凝土板劣化后的多层分析模型，相应建立了混凝土老化后的应力－应变，内力－应变关系和平衡方程；并 均布载荷作用下简支板的弯曲变形。

A Research on the Deflection of the Aging RC Plate

Based on the experimental result,a multi-layer analysis model of the deteriorated RC plate was formed to better identify the state of deterioration.Correspondingly,the relationships between strss and stain and between eigenforces and strain were established the equillibrium equation was formulated and the deflection function of simple-support plate subjected to a uniformly distributed load was inspected.Different deflection deformations for the fresh and aging RC plates were obtained through programed calculation.By comparing delections of different layers in RC plate,a conclusion has been reached that a greater attention must be paid to outer layer deteriorating of the RC plate in safety assessment.
